{"version":"1.0","type":"rich","title":"World Population by 2015","description":"This visualization shows the growth of world population from 1960 to 2015 using a filled area chart with a smooth curved baseline. The code uses d3.csv to load the data, then applies d3.scaleTime and d3.scaleLinear for the x and y axes, with d3.area and d3.curveBasis to generate the path. Axis labels and a title are added via SVG text elements, and grid lines are drawn through tick sizes. The y-axis formats values in billions using d3.format.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e7e43814c71848379f1e72597bc4c046?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
